Find all subsets of set power set in java
WebI like this approach because it is more aligned with the mathematical definition of power set (set of all subsets). def power_set(A): """A is an iterable (list, tuple, set, str, etc) returns a set which is the power set of A.""" length = len(A) l = [a for a in A] ps = set() for i in range(2 ** length): selector = f'{i:0{length}b}' subset = {l[j ... WebApproach 2. For a given set S, the power set can be found by generating all binary numbers between 0 and 2 n -1, where n is the size of the set. For example, for the set S { x, y, z }, generate binary numbers from 0 to 2 3 -1 and for each number generated, the corresponding set can be found by considering set bits in the number. 0 = 000 = {}

Approach 1. Take the first element of your number list; generate all subsets from the remaining number list (i.e. the number list without the chosen one) => Recursion!; for every subset found in the previous step, add the subset itself and the subset joined with the element chosen in step 1 to the output.
